@ 1kHz
* AC Electrical Characteristics are over Recommended Operating Conditions unless otherwise stated.
† Typical figures are at 25°C with nominal + 5V supplies and are for design aid only.
‡ Max and Min figures guaranteed over 0°C to 70°C only.
Notes: Impedance set to variant impedance
Test conditions uses a Z
in
value as specified by variant number.
Test conditions use a transmit and receive gain set to 0dB default and a Z
in
value of 600Ω unless otherwise stated.
